Vacuum Chamber Gas Bag Sampler

Product Overview

The Vacuum Chamber Gas Bag Sampler is a professional device for gas sample collection, designed to capture gaseous pollutants from ambient air and industrial emissions, with particular suitability for volatile organic compounds (VOCs). The sampler employs a gas bag method under vacuum chamber negative pressure, minimizing direct contact between the sample and the device, effectively preventing cross-contamination. It is widely used in environmental monitoring, public health, occupational safety, supervision, military, research, and educational applications, providing a reliable solution for high-quality gas sampling.

Working Principle

The sampler generates negative pressure through a vacuum chamber, enabling gas collection into an inert gas line and gas bag. This design avoids direct contact between the sample and the sampler, preventing contamination or adsorption losses. A directional switch allows rapid replacement of residual gas in the gas bag with new gas, ensuring sample purity. An internal high-performance lithium battery powers the device, enabling flexible, field-ready sampling without external power supply.

Key Features

• Vacuum Negative Pressure Sampling: Ensures sample integrity by avoiding direct contact with the sampler and eliminating cross-contamination.
• Easy Gas Replacement: Residual gas in the bag can be quickly replaced and fresh samples collected via the directional switch.
• Inert Gas Path Design: Sampling lines use inert materials to prevent sample contamination or adsorption loss.
• High-Performance Lithium Battery: Supports portable operation without the need for external power.
• Wide Applicability: Suitable for VOCs and other gaseous pollutants in environmental and industrial monitoring.

Applications

• Environmental Monitoring: Sampling gaseous pollutants from industrial emissions, especially VOCs.
• Odorous Gas Detection: Compliant with the “Three-Point Bag Method for Air Quality Odor Measurement” standard for environmental odor monitoring.
• Indoor Air Quality Monitoring: Collects gaseous pollutants in indoor environments to safeguard work and living spaces.
• Occupational Safety & Supervision: Suitable for chemical storage and processing areas to monitor gas emissions and ensure environmental safety.
• Research & Education: Widely applied in research institutes and universities for air pollution studies and educational experiments.
